func ComposeUserData ¶

func ComposeUserData(icfg *instancecfg.InstanceConfig, cloudcfg cloudinit.CloudConfig, renderer renderers.ProviderRenderer) ([]byte, error)

ComposeUserData fills out the provided cloudinit configuration structure so it is suitable for initialising a machine with the given configuration, and then renders it and encodes it using the supplied renderer. When calling ComposeUserData a encoding implementation must be chosen from the providerinit/encoders package according to the need of the provider.

If the provided cloudcfg is nil, a new one will be created internally.
